FIELD: charging chemical current supplies. SUBSTANCE: proposed method can be used for charging and recovering nickel-cadmium (Ni-Cd), nickel-metal hydride (Ni-MH), and lead batteries. Novelty is that batteries are charged with asymmetric pulse current using alternating charge and discharge pulses, and mechanical vibrations are set up in battery due to generation of charge pulse in the form of high-frequency pulse train. Frequency of pulses constituting charge pulse is chosen between 3 and 30 kHz. High-frequency current pulses cause mechanical vibrations in battery at same frequency which augments electrochemical processes, facilitates access of electrolyte to active material of plates, and improves gas motion conditions for recombination process. Discharge pulses encourage crushing of coarse crystalline structures on surfaces of battery cells, and mechanical vibrations set up in battery contribute to this process. EFFECT: reduced charge internal resistance and warm-up period of battery. 2 cl, 1 dwg
